ticularly adaptedlforusein connection with ditches for dredging the sand, silt and other matter which washes into ditches and raising to a position so that it flows with and serves for irrigating and fertilizing soiladjacent theditch andthe obJects-of my invention are: first, to provide a dredger wherein the digging device alsoserves for raising the siltandother material from the ditch npwardlyto a position so that it will flow out over the banksroflthe ditch; second, to iprovidea dredger of this class in which the digging device also serves to move the dredger along as required for cleaning the ditch, and with means for retarding the movement as desired; third, toprovide a dredger of-this class inwhich the conducting pipe serves as a conductor forthe dredged material from thedredger aswell as an axle for the dredger so that the conductor is re olv her y e p ng the t ia a ated and. pr e g i pa ng n th n- .cluctor; fourth, to provide anovelly constructed dredger and fifth, to provide a dredger of this class which'is very simple and economical of construction, durable, easy to operate, efficient in its action and which will not readily deteriorate or get out of orderl Vith these and other objects in view as will appear hereinafter, my invention consists of certain novel features ofconstruction, combination and arrangementv of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claims, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which; i

The float 1, engine 2, belt 3, combined 3' conductor and axle 4, tubes 7 5, trap doors6 ear n s" 7, upp e ard 9, abl 0 nd wiiiCllass l1 constitute the principal parts an pqrt i o m dred The float 1 t is of suitable width 7 and length for the purpose used, it being noted that for cleaning. ditches and: the like, it

should be long narrow shown best in the drawingsf This floatis providedon one end, preferably" the front end, With a motor 2 and'revolubly mounted across said float is a' tubular member 4;,mountiecljin the bearings 7 which are supported onfopposite sides of the float .1. This float 1 is provided with I I an opening} therethroughand secured to the .pipeel, and adapted to extend through the opening when turned inthe. proper re- 'lative' p sit m. r a r e of l w v d tubular members 5, so arranged that only one or two are adapted to' engaget'he digns arim a ti when re olv d' e nection with the tubular memberi i. These curved" tubular members are provided at their i e d p eferab with sharp;

ened edges a'daptedas diggers and on their inner ends where they extend through the tubular niember 4c are provided trap doors 6 forenclosing'their inner jenfdsjan'd providedwith torsion springs 6 shown best I i i in Fig. ntending to hold said doorsti closed but permitting their opening when pressure is brought to bear against said trap doors 6. The outer ends of these tubular members 5 are supported by means of braces 5 It will be noted that in they illustration which is a part ofthis application, thereis" shown three rows of curved tubes with four tubes in each row and eachsecl l'ed to the tubular member 4 and adaptedtO QVDlVeJWith said.

tubular member and engagetlie bottom tion of theditch, one eiidat a time, in such a m nner asto ead'tomov lth floa 11 h? direction it is desired todig, or lower the bottomhoflthe ditch so that'withgthe revbtubular member 4 and also that with the revolution of said members the sand, silt and water are gravitated until the pressure opens the trap doors 6 and permits the same to flow into the tubular member 4 which extends outwardly over the banks of the ditch so that said sand, silt and water passes out over the banks of the ditch which results in removing the sand and silt from the bottom of the ditch, carrying it together with some water from the ditch over the banks where it will spread in a thin substance over the top surface of the ground, thus irrigating and fertilizing the ground adjacent the ditch. Mounted on the back of the dredger is a support 8, upon which is pivotally mounted a retarding member 9'which extends downwardly adapted to engage the bottom of the ditch for retarding the movement of the dredger as desired, and this retarding member 9 is supported by means of a cable 10 wound on a Windlass 11 so that the retarding member 9 may be operated as desired for retarding the movement of the dredger forwardly in the ditch.

In the modified form of construction, shown in Figs. Sand 6 of the drawings, the extended ends of the curved tubular members 6 are reduced in size on their inner and side surfaces so that there is provided clearance for the silt, dirt and sand shortly after it passes the end so that it will flow readily into the tubular member 4 and not pack in the tube 6 which might be necessary in some substances.

Though I have shown and described a particular construction, combination and ar rangement of parts and portions and a certain modification thereof I do not wish to be limited to this particular construction, combination and arrangement, nor to the modification but desire to include in the purview of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

It is obvious that with this construction, there is provided a dredger in which sand, silt and other substances may be readily removed and raised to an elevation and conducted to a place desired; that the dredger may be moved and retarded from movement to regulate the conditions to be met; that the dredging device performs the functions of digging, raising the substance dug, conducting it to the position desired, moving the dredger and keeping the conductor revolving, thereby agitating the substance therein to prevent its clogging; that it is believed that the pressure caused by the impact of the ends of the tubes 5 with the sand and other substances will cause air and water pressure for forcing the substance from the tubular member 4:; that in addition to this, gravity of the substance together with the water will cause the pressure for forcing the substance from the tubular conductor 4:.

Having thus described my invention what I claim as new and desire to secure by Let-' ters Patent is:

1. A dredger, including an outwardly ex tended revolubly mounted tubular axle positioned substantially above the ground to be removed, a plurality of curved digging and conducting members communicating with the interior of said axle and means for revolving said tubular axle together with said curved digging and conducting members.

2. A dredger, including an outwardly extended revolubly mounted tubular axle positioned substantially above the ground to be removed, a plurality of curved digging and conducting members communicating with the interior of said axle, trap doors for closing the openings from said curved members to said extended tubular axle, means for revolving said tubular axle together with said curved digging and conducting members and a float member upon which said revoluble tubular member is supported.

3. A dredger, including a float, a tubular axle revolubly mounted on said float and extending over the edge of the same, a plurality of curved tubular members with one end communicating with said tubular axle and their other open end extending -outwardly therefrom and means mounted on said float for revolvin said tubular axle.

4. A dredger, including a float, a. tubular axle revolubly mounted on said float and extending over the edge of the same, a plurality of curved tubular members with one end communicating with said tubular axle and their other open end extending outwardly therefrom, means mounted on said float for revolving said tubular axle and a trap doormounted over the inner ends of said tubes adapted to regulate the flow of substance from said curved tubular members to said extended tubular axle, dependent upon the pressure of the substance in said curved tubular members,

5. A dredger, including afloat, a tubular axle revolubly mounted on said float and extending over the edge of the same, a plurality of curved tubular members with one end communicating with said tubular axle and their other open end extending outwardly therefrom, means mounted on said float for revolving said tubular axle, a trap door mounted over the inner ends of said tubes adapted to regulate the flow of substance from said curvedtubular members to said extended tubular axle, dependent upon the pressure of the substance in said curved tubular members and means mounted on said float for retarding the forward movement of said float.

6. A 'dredger, including a revolubly mounted tubular axle, a plurality of'curved digging, conducting and propelling mem bers and a portable support upon which said revoluble tubular member is supported.

7 7. An apparatus of the class described, in-

cluding'a portable support, a laterally extended discharge tube revolubly mounted, on said support, ,a'plurality of combined digging, conducting and propellingmembers I secured'to and communicating with said dis charge tube and discharge regulating means positioned in said discharge tube adjacent a to the ends of said digging, conductingand propelllng members communicating 'with said discharge tube. i i

In testimony whereof, I have hereunto set my hand at San Diego, California this 16th day of November 1920.
